DESCRIPTION
"The type of algorithm used by this dropper. A value
of tailDrop(2), headDrop(3), or alwaysDrop(5) represents
an algorithm that is completely specified by this PIB.
A value of other(1) indicates that the specifics of
the drop algorithm are specified in some other PIB
module, and that the dsAlgDropSpecific attribute
points to an instance of a PRC in that PIB that
specifies the information necessary to implement the
algorithm.
The tailDrop(2) algorithm is described as follows:
dsAlgDropQThreshold represents the depth of the
queue, pointed to by dsAlgDropQMeasure, at
which all newly arriving packets will be dropped.
The headDrop(3) algorithm is described as follows: if
a packet arrives when the current depth of the queue,
pointed to by dsAlgDropQMeasure, is at
dsAlgDropQThreshold, packets currently at the head of
the queue are dropped to make room for the new packet
to be enqueued at the tail of the queue.
The randomDrop(4) algorithm is described as follows:
on packet arrival, an algorithm is executed which may
randomly drop the packet, or drop other packet(s)
from the queue in its place. The specifics of the
algorithm may be proprietary. For this algorithm,
dsAlgDropSpecific points to a dsRandomDropEntry
that describes the algorithm. For this
algorithm, dsAlgQThreshold is understood to be
the absolute maximum size of the queue and additional
parameters are described in dsRandomDropTable.
The alwaysDrop(5) algorithm always drops packets. In
this case, the other configuration values in this Entry
are not meaningful; The queue is not used, therefore,
dsAlgDropNext, dsAlgDropQMeasure, and
dsAlgDropSpecific should be all set to zeroDotZero.
The mQDrop(6) algorithm measures multiple queues for
the drop algorithm. The queues measured are represented
by having dsAlgDropQMeasure referencing a dsMQAlgDropEntry.
Each of the chained dsMQAlgDropEntry is used to describe
the drop algorithm for one of the measured queues."

-- Minimum Rate Parameters Table
--
-- The parameters used by a scheduler for its inputs or outputs are
-- maintained separately from the Queue or Scheduler table entries
-- for reusability reasons and so that they may be used by both
-- queues and schedulers. This follows the approach for separation
-- of data path elements from parameterization that is used
-- throughout this PIB.
-- Use of these Minimum Rate Parameter Table entries by Queues and
-- Schedulers allows the modeling of hierarchical scheduling
-- systems.
--
-- Specifically, a Scheduler has one or more inputs and one output.
-- Any queue feeding a scheduler, or any scheduler which feeds a
-- second scheduler, might specify a minimum transfer rate by
-- pointing to a Minimum Rate Parameter Table entry.
--
-- The dsMinRatePriority/Absolute/Relative attributes are used as
-- parameters to the work-conserving portion of a scheduler:
-- "work-conserving" implies that the scheduler can continue to emit
-- data as long as there is data available at its input(s). This
-- has the effect of guaranteeing a certain priority relative to
-- other scheduler inputs and/or a certain minimum proportion of the
-- available output bandwidth. Properly configured, this means a
-- certain minimum rate, which may be exceeded should traffic be
-- available should there be spare bandwidth after all other classes
-- have had opportunities to consume their own minimum rates.
